All military reasons on the side of Pompeius favoured the view, that the decisive battle should not be long delayed, seeing that they now confronted Caesar in Thessaly; and the emigrant impatience of the many genteel officers and others accompanying the army doubtless had more weight than even such reasons in the council of war. Since the events of Dyrrhachium these lords regarded the triumph of their party as an ascertained fact; already there was eager strife as to the filling up of Caesar's supreme pontificate, and instructions were sent to Rome to hire houses at the Forum for the next elections. When Pompeius hesitated on his part to cross the rivulet which separated the two armies, and which Caesar with his much weaker army did not venture to pass, this excited great indignation; Pompeius, it was alleged, only delayed the battle in order to rule somewhat longer over so many consulars and praetorians and to perpetuate his part of Agamemnon. Pompeius yielded; and Caesar, who under the impression that matters would not come to a battle, had just projected a mode of turning the enemy's army and for that purpose was on the point of setting out towards Scotussa, likewise arrayed his legions for battle, when he saw the Pompeians preparing to offer it to him on his bank.
The Battle
Thus the battle of Pharsalus was fought on the 9th August 706, almost on the same field where a hundred and fifty years before the Romans had laid the foundation of their dominion in the east.(31) Pompeius rested his right wing on the Enipeus; Caesar opposite to him rested his left on the broken ground stretching in front of the Enipeus; the two other wings were stationed out in the plain, covered in each case by the cavalry and the light troops. The intention of Pompeius was to keep his infantry on the defensive, but with his cavalry to scatter the weak band of horsemen which, mixed after the German fashion with light infantry, confronted him, and then to take Caesar's right wing in rear. His infantry courageously sustained the first charge of that of the enemy, and the engagement there came to a stand. Labienus likewise dispersed the enemy's cavalry after a brave but short resistance, and deployed his force to the left with the view of turning the infantry. But Caesar, foreseeing the defeat of his cavalry, had stationed behind it on the threatened flank of his right wing some 2000 of his best legionaries. As the enemy's horsemen, driving those of Caesar before them, galloped along and around the line, they suddenly came upon this select corps advancing intrepidly against them and, rapidly thrown into confusion by the unexpected and unusual infantry attack,(32) they galloped at full speed from the field of battle. The victorious legionaries cut to pieces the enemy's archers now unprotected, then rushed at the left wing of the enemy, and began now on their part to turn it. At the same time Caesar's third division hitherto reserved advanced along the whole line to the attack. The unexpected defeat of the best arm of the Pompeian army, as it raised the courage of their opponents, broke that of the army and above all that of the general. When Pompeius, who from the outset did not trust his infantry, saw the horsemen gallop off, he rode back at once from the field of battle to the camp, without even awaiting the issue of the general attack ordered by Caesar. His legions began to waver and soon to retire over the brook into the camp, which was not accomplished without severe loss.
Its Issue Flight Of Pompeius
The day was thus lost and many an able soldier had fallen, but the army was still substantially intact, and the situation of Pompeius was far less perilous than that of Caesar after the defeat of Dyrrhachium. But while Caesar in the vicissitudes of his destiny had learned that fortune loves to withdraw herself at certain moments even from her favourites in order to be once more won back through their perseverance, Pompeius knew fortune hitherto only as the constant goddess, and despaired of himself and of her when she withdrew from him; and, while in Caesar's grander nature despair only developed yet mightier energies, the inferior soul of Pompeius under similar pressure sank into the infinite abyss of despondency. As once in the war with Sertorius he had been on the point of abandoning the office entrusted to him in presence of his superior opponent and of departing,(33) so now, when he saw the legions retire over the stream, he threw from him the fatal general's scarf, and rode off by the nearest route to the sea, to find means of embarking there. His army discouraged and leaderless-- for Scipio, although recognized by Pompeius as colleague in supreme command, was yet general-in-chief only in name--hoped to find protection behind the camp-walls; but Caesar allowed it no rest; the obstinate resistance of the Roman and Thracian guard of the camp was speedily overcome, and the mass was compelled to withdraw in disorder to the heights of Crannon and Scotussa, at the foot of which the camp was pitched. It attempted by moving forward along these hills to regain Larisa; but the troops of Caesar, heeding neither booty nor fatigue and advancing by better paths in the plain, intercepted the route of the fugitives; in fact, when late in the evening the Pompeians suspended their march, their pursuers were able even to draw an entrenched line which precluded the fugitives from access to the only rivulet to be found in the neighbourhood. So ended the day of Pharsalus. The enemy's army was not only defeated, but annihilated; 15,000 of the enemy lay dead or wounded on the field of battle, while the Caesarians missed only 200 men; the body which remained together, amounting still to nearly 20,000 men, laid down their arms on the morning after the battle only isolated troops, including, it is true, the officers of most note, sought a refuge in the mountains; of the eleven eagles of the enemy nine were handed over to Caesar. Caesar, who on the very day of the battle had reminded the soldiers that they should not forget the fellow-citizen in the foe, did not treat the captives as did Bibulus and Labienus; nevertheless he too found it necessary now to exercise some severity. The common soldiers were incorporated in the army, fines or confiscations of property were inflicted on the men of better rank; the senators and equites of note who were taken, with few exceptions, suffered death.
